A TTORNE v5 JOSEPH TAYLOR, OF LUDINGTON, MICHIGAN.

ROLLER-BEARING.

Specification of Letters Patent.

Patented June 30, 19 38.

Application filed October 12, 1906. Serial No. 338,651.

To all whom it may concern:

Be it known that I, JosEPn TAYLOR, a citizen of the United States, residing at Ludington, county of Mason, and State'of Michigan, have invented new and useful Improvements in Roller-Bearings, of which the following is a specification.

My invention relates to improvements in roller bearings.

The objectof my invention is to provide a roller bearing for car axles which will run without oil, and in which the rollers will not wear flat, the rollers being free to shift in the box during an end thrust, so that the relative positions of the rollers to the axle is unchanged.

My invention also relates to certain improvements in the structure of the bearing, iercinafter described and claimed.

In the following descri tion reference is bad to the accompanying rawings in which,

Figure 1 is a vertical sectional view, drawn on the axis of the axle shaft, Fig. 2 is a cross sectional View drawn on line x-w of Fig. 1. Fig. 8 is an end view. Fig. 4 is a sectional view on lines y y of Fig. 1 showing the packin sheet.

ike parts are identified by the same refer ence characters throughout the several views.

The axle shaft 1 is provided with a reduced end portion 2 and with a shoulder 3 which abuts a set of rollers 4 carried by a cylindrical casing 5. The casing 5 has an inturned roller-retainin annular flange 6 at one end, with a centraT opening through which the axle shaft 1 extends, and at the other end a roller retaining angle iron ring 7 is secured to the interior surface of the casing by bolts 8,

the heads of which engage in lon itudinal channels 9 in the box 10, which inc oses the end of the axle, roller casing, and rollers. The interior of the box is of a generally cylindrical form to correspond with the contour of the casing, but the upper outer surface of the casing is flattened and the box is provided with a rectangular recess a opposite this fiat surface of the casing, which recess receives a series of rollers 14, adapted to support the load carried by the box.

The inner end of the box is provided with a wall 15 having a central aperture for the axle shaft and a slot or recess extends inwardly from the upper side to a point below this aperture and receives a sheet of packing 17, preferably formed of felt and having an aperture 18 for the shaft as shown in Fig. 4.

This packing excludes dust iron) the hearing. The outer end of the box is provided with a lid 19, connected with the upper portion of the box by a hinge bolt 20, which also sup- )orts an arched spring 21 in a position to car a ainst the central and lower portions of the id and hold it tightly in closed position. I

The load is supported from the shaft through the rollers 4i, casing 5, rollers 14, and box 10. In case of an end thrust the friction of the axle on rollers 4 will retain those units in their relative position while the loose rollers 14 permit the box and roller casing to shift relatively on longitudinal lines. With this construction the rollers 4 will not wear flat but will preserve a true cylindrical form. The shifting movement of the roller casing in the box is limited in one direction by the end wall 15 and in the other direction by bolts 28, but the axle shaft will normally hold the casing in an intermediate position. It will be observed that in the construction illustrated the axle shaft is without collars or projertions of any kind exce t the shoulder 3. ,The similar journal at t 1e other end of the axle prevents it from pulling out longitudinally. The heads of the bolts 8 in the channels 9 prevent the casing from shifting annularly in the box.

Having thus describedmy invention what I claim as new and desire to secure by Letters Patent is,

' 1. In a bearing of the described class the combination of an axle having a reduced end; a casing inclosing the end of the axle; rollers loosely interposed between the casing and the shoulder at the reduced end of the axle; a journal box loosely inclosin the casing and recessed on one side interme iate. of its ends and a set of loose rollers in said recess disposed transversely to the axle and supporting the box from the casing; said casing having a flat bearing surface for said rollers; together with a roller retaining flange in the outer ends of the casing, and bolts connecting the casing and flange, with the bolt heads rejecting into longitudinal channels in the 2. In a bearing of the described class the comblnatmn of an axle having a reduced end; a casing inc-losing the end of the axle; rollers loosel interposed between the i casing and reduce end of the axle; a journal box loosely inclosing the casing and recessed on one side,- and set of loose rollers in said recess disposed transversely to the axle and supporting the box from the eas- 1 ingz'sutd easm inn-lug n tlat bearing snrface for Sftid rolTers, the inner end of said box being a )Grtured for the rs- 'eptiun of t he slmit back 0 the reduced end )ortion and slotted portion with an abrupt shoulder at the inner end of said portion. :1 ensntg in swing the end of the axi and provided tilt :tn 1n turned flange at its inner end, an angle n'on having :r not hearing surfzzee for the transversely disposed rollers and said journal box being n'ovided with slots for the reee tion of the ads of the easing guide bolts, u' hereby the easing is held ngninst rotation.

4. in a bearing of tin-described class the eoinbinntion of an axle lnn'in g n redueed end; :1 easing iIHltMlHg the end of the axle; rollers loosely interposed betueen the casing and redueed end of the axle: a journal box loosely inelosin; the casing and reeessed oh one side intermediate of its ends; and a set of loose rollers in said reeess disposed transversely to 'the axle and sn -ipoi'ting the box from the ring secured at the outer end of the ensing,

loose roiltirs interposed be'tueen the ring and shoulder, a jOUIlltll box loosely llleinsillg the casing and recessed on one side intermediate its ends, a set of loose rollers in said 'i'eeess disposed transversely to the axle and supporting the box from tho neutg. lHiliS extending through the oute: end of the casin and serving as guides, and bolts extending through the outer end pol! ton oi the, lournnl box in a position to serve as stops limiting 1 the movement of the i'flfiiillg."" iiilti. easing easing; snid ensing hnving n tint bearing: nt't'uee for said roller said easing having inturned roller retaining flanges at its re'speetive ends, and said box being provided with means for limiting the longitudinal movement of the easing therein.
